UNLOADING DEVICE.

Application filed August 9, 1917.

2'?) all v /iom it may concern:

lie it known that I, Janus HA'rnir-F Yuanwoon. a citizen of the UnitedStates. residing at Lima. in the county of Allen and State of Ohio. haveinvented certain new and useful Improvements in Unloading Devices; and 1do declare the following to be a full, clear. and exact description ofthe invention. such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has for its object to provide a simply constructed andinexpensive. yet a highly etlieieut and durable device for un loadingrailwav cars and barges, and with this general object in view. theinvention resides in the novel features of construction and uniouecombination of parts to be hereinafter fully described and claimed. thedcseriptive matter being supplemented by the accompan ing drawings whichform part of this specification and in which:

Figure 1 is a perspective view of the invention before the scoop isloaded, and

F g. 2 is a similar view after loading and ra sing of the scoop.

in the drawing above briefly described the numeral 1 des gnates ahorizontal supporting bar adapted to rest on the upper edge of a carbodv or l'iarge. suitable clamps 2 being provided for securing said barin place. To prevent possible upward tilting of the bar 1. a hook or thelike preferably depends therefrom for passage under the car or barge. atu nbuckle 4 being shown for drawinn the bill of the hook to operativeposition.

The outer end of the bar 1 extends beyond he bodv of the car or bargeand is provided w th a stub 5 upon which a vertical swinging lever 6 isfulcrumed between its ends. one end of said lever being directedlaterally as shown at 7 to overlie the body of the car or the like.whereas the other end 8 of the lever 6 preferably inclines downwardlyfrom the body portion thereof. The laterally extending end 7 carries asheave 9 or other appropriate cable guide whereas a similar guide 10 ismounted on the opposite end of said lever, while two or more additionalguides 11 are by preference employed at the two angles.

A cable 12 is trained around the guides 9, 10 and 11, and at one end issecured to a bucket 13 which is shown in the form of acommon type ofscoop. The other end of Specification of LettersPatent.

Patented Mar. 5, 191 8.

Serial-No. 185,350.

the cable 12 passes around a pulley or the like 1.4 which is spaced fromthe guide 710 and located in the plane of movement ofthe lever, saidcable also passing around another pulley .15 and than continuing to anysuitable pulling means such as a Windlass or a snatch team. The pulley14 will in most cases be provided with a chain orother suitable anchor=16 by which it may be secured to the draw bar B when the device iscmployed upon a railway car, said anchor serving the same function whenthe improved mechanism is used on a barge. it being neces sary, however,to secure said anchor to another appropriate part. The pulley 15 ismounted on a suitable block 17 having a chain or the like 18 by which itmay be ant-lwred to one of the rails of a track or to another suitablerelatively fixed member, the block 17 also carrying an additional pulley15 whose function will hereinafter appear.

As shown clearly in Fig. 1, the lever 6 is normally positioned insubstantial and horizontal plane with its lateral directed end 7 restingupon the upper edge of the barge or car body, said lever being held inthis position by any preferred means such as the bolt 19 illustrated inthe drawings. said bolt being shown mounted upon an appropriate clamp 20whereby it may be attached andidetached as occasion may demand when thecable 12 has been ulled to the required extent. however, to oad thescoop 13 and to draw this scoop to the end 7 of the lever 6, the bolt 19will be released either by hand or otherwise, so that a further pullupon the cable will move the end 8 of the lever toward the pulley 14. Inso moving, the lever 6 raises theloadcd scoop above the edge of thebarge or car so that it maybe dumped upon a chute 21 to load thematerial into a Wii on or thelike provided for the urpose. 1c chute 21is preferable secure to the bar 1 but it might obviously be mounted inan other preferred manner or the lever 6 coul be of such construction asto permit its lateral end 7 to swing beyond the car or'barge so that thescoop 13 could be dumped dircctly into a. wagon or the like without thenecessity of employing a chute.

Any preferred means could Well be em ploycd for returning the scoop 13to any require-d point within the car or barge, but for this purpose Ipreferably employ a second cable 22 which is secured at one end to thescoop 13 whereas the other end of said cable passes around the pulley 15and leads to a Windlass or any other preferred means which may beemployed for pulling upon said cable when required. The intermediateportion of cable 22 is trained around a pair of guide pulleys 23preferably having clamps 24 by means of which they may be secured to andadjusted along the end of the barge or car remote from the lever 6.

From the foregoing, taken in connection with the accompanying drawings,it will be obvious that I have provided a comparatively simple andinexpensive arrangement of parts for carrying out the object of the invention, yet that the device will be highly efficient and durable forthe two uses specified as well as for any other purpose to which it maybe found applicable. On account of the several advantages resulting fromthe features of construction shown and described, this constructionconstitutes the preferred form of the improved unloading device but Iwish it understood that within the scope of the invention as claimed,numerous minor changes may well be made without sacrificing theprincipal advantages. Furthermore the invention is not restricted in useto any particular field, but may be used for the unloading of cars,barges, storage bins, etc., and for excavating or removing all sorts ofmaterial. The device may be mounted on either a fixed or movable objectand may be operated by Windlass, horse power, gasolene or steam power,electricity, etc.

I claim 1. In a hoisting device, the combination of a support, a lateralprojection extending horizontally from said support, a verticallyswinging lever fulcrumed between its ends on said projection andnormally disposed in substantially a horizontal position, one arm ofsaid lever being extended laterally in a horizontal direction at a pointspaced from the fulcrum, a pulley at each end of said lever and one atthe angle thereof, a hoisting cable trained around said pulleys anddepending from the lateral end of said lever, and means on saiddepending cable end for engagement with the material to be hoisted, theother end of said cable being adapted to be pulled, whereby to raise theload to the lever and to then swing said lever to a substantiallyvertical position.

copies of this patent may be obtained for five cents each, by addressingthe 2. In a hoisting device, the combination of a horizontal bar andmeans for securing it to a box with one end extending therefrom, avertically swinging lever fulcrumed between its ends on. said end ofsaid bar, one arm of said lever being extended laterally in a horizontaldirection at a distance from the fulcrum and located in substantiallyparallel relation with said bar, whereby to overlie the upper edge ofthe box and limit the swinging movement of the lever in one direction,pulleys on the ends of said lever and at the angle thereof, a hoistingcable trained around said pulleys and depending from the lateral end ofsaid lever, and means on the depending cable end for engagement with thematerial to be hoisted, the other end of said cable being adapted to bepulled, whereby to raise the load to the lever and to then swing saidlever to a substantially vertical position.

3. In a hoisting device, the combination of a box having an open top andcontaining the material to be hoisted, a horizontal bar secured to theupper edge at one side of said box and projecting beyond one endthereof, a vertically swinging lever fulcrumed between its ends to theprojecting end of said bar, said lever operating in a plane parallel tosaid end of the box and having one of its ends bent laterally toposition its terminal. above the box, said laterally bent end normallyresting on the upper edge of said end of the box to limit the movementof the lever in one direction, releasable means for holding said leverin this position, a pulley at each end of said lever, other pulleys atthe angle of said lever and adjacent the fulcrum thereof, a hoistingcable trained around said pulleys, and a bucket secured to the end ofsaid cable adjacent said lateral end of the lever, the other end of saidcable being adapted to be pulled to raise the loaded bucket against thelever and to swing said lever to substantially a vertical position whenthe holding means thereof is released.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
